About Sega Master System
The Sega Master System (1985/1986) was Sega's answer to the NES and, while it lost the console war in North America, became genuinely dominant in markets like Brazil and parts of Europe. That regional split matters for collectors: PAL and Brazilian-market cartridges can differ meaningfully in scarcity and pricing from their North American counterparts for the same title.
Gamevaro tracks Bonanza Bros. for Sega Master System with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Bonanza Bros. to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This SMS release dates back to 1990.

No market sales have been tracked yet for Bonanza Bros. — this could mean it rarely changes hands, or simply that Gamevaro hasn't recorded a sale for it yet. Be the first to add it to your collection.
Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
